Scanning optical delay device having a helicoid reflecting mirror |
摘要 |
A rapid and linear scanning optical delay line was attained by the use of a helicoid reflecting mirror which was spun by a DC servo motor for bringing about a periodic change in the optical path length of the reflected light beam. The double-pass scanning range of the delay time as large as 80 picosecond was attained by the scanning optical delay line having a helicoid reflecting mirror having 12 mm in pitch distance. The scanning optical delay line was used in an optical second-harmonic generation autocorrelator, which was thus capable of scanning successfully a picosecond optical pulse train. A real-time scanning of the picosecond laser pulse of a mode-locked Titanium:Sapphire was verified.
